How they compare: the verdict
Amino USA takes this matchup by a razor-thin margin, 7.78 to 7.68 on the published formula. Its biggest edge is transparency, where it scores 6.5 against Loti Labs's 3.0.
It isn't a clean sweep. Loti Labs actually edges ahead on operating history (7.2 vs 4.2), so if that factor matters most to you it's worth weighing.
On lab evidence, the heaviest-weighted factor, both Amino USA and Loti Labs have independently verified third-party COAs, so the gap comes down to the other categories.
Across the 19 peptides both carry, Amino USA is cheaper per unit more often (Amino USA wins on 16, Loti Labs on 3). The price-for-price table below has the detail, per mg (or per IU or mL for products sold that way).
